Ok got rid of everything now i need to know the factory carb settings so i can get this thing to start without starter fluid. It wont idle till warm and needs the airbox choked to run. Anyone know them?
I'm going to look for a tutorial on checking the valves as well to make sure i know what they are supposed to be set and how to do it. Looks like .004 and .005. Uhg its always something. My feeler only goes to .008. Time to go shopping.

.... Never understood why most motors run a breather into the air cleaner,,its such a bad design,,makes for a mess everywhere and really doesn't help the environment out anymore IMO... The breather from the valve cover to the air intake allows the small amount of vapors to be redirected back into your engine. It's not only about the ecological benefits, it's supposed to help with mileage as well, since those vapors are mostly fuel, and they get re-used in this sort of system. IMHO, this is just jumping the shark, so I just add a fuel filter to the valve cover breather tube and and zip tie it high up on the frame. I tested fuel consumption before and after removing the airbox on mine, after removing it it got me 8mpg more and better performance, my airbox went straight to the trash bin  |

The enricher tested good. I fixed the tear on the diaphragm on the side where the vac line comes in. Need to set the baseline on the mixture screw, how many turns from factory? Anything else i can do to it?      I have plugged everything, tank and all vac wise except the intake to carb. Here's everything I threw out  What it looks like now (A lot cleaner without those lines everywhere).  Plugged this:  This connects to....  This here:  And these two got plugged up.  |

This connects to.... That images looks like the vent line for your gas tank. Follow it and see ifit leads to the top of the tank. If so, unplug it, put a fuel filter on it if you have one, the let it be. If plugged that could be part of your problem if you don't have a hole drilled in your gas cap. As for the A/F screw, try backing it in all the way then letting it out 2-2.5 turns. It's hard to say without knowing the needle position and jet size. But that should get you into the ballpark of running. So now all you have connected to vacuum line is the carburetor? |

Yeah i removed that before i tried to start it. Corrct on vac line to carb. Here you can hear it almost hitting, but it never catches. Have to use start fluid to get it to fully start.
Sooooo close

You don't play with the throttle when starting a GY6. You may be flooding it, especially since I believe your have a carb with an accelerator pump, it squirts in extra gas each time you turn the throttle. Try turning your a/f all the way in, then back it out 1.5 turns. Just to be sure, you do have the manual fuel petcock turned on when attempting to start it?
If you can't get it to fire with the a/f at 1.5 turns, you need to check your valves. Improperly set valves are the number one cause of hard starting on a GY6.

I have let it try to hit without my help and it seems to try more with a slight burp but idk. Valves are a definite today before its over.

thats a 150cc carb no pump . However i think its a fuel problem . and Jerry is correct leave the throttle alone . squirt some fuel in the vac line and see if you can crank it started or get a short run .

All I have to do is shoot it with starter fluid and it will run fine the whole tank from there it just won't start and before it warms up it will not actually run at idle it just tries to basically drop back off very quickly from over half a throttle to a dead cutoff. Once its warm it will hold idle just below where the clutches engage.

Choking the intake would increase vacuum, perhaps pulling more fuel out of the jets. |

Uhg its always something. My feeler only goes to .008. Time to go shopping. The first time I did my valves I used a slice of a CocaCola can. It was better than nothing and you can bet their cans are made to tight tolerances so chances are they are all pretty much the same thickness. I have a nice set of feelers now but it's a nice thing to know you can get away with a can in a pinch. |

Nice looking scoot! Congrats on the deal. Crunk Man! Where you been? How is your vlog coming along? I've been COLD. Haha. Seriously though just got all caught up in the holidays and whatnot so I haven't been around online as much. I'm still working on getting a suitable microphone setup going which is going to involve hacking my "NoPro", SJ4000 cam to give it a microphone in port. After that I'm in business! ...just in time for it to be a constant 30 degrees outside. :-p |
